BOOK FOR STAMPS.

SPECIFICATION forming part of Letters Patent No. 520,399, dated May 22, 1894. Application lecl May 1,1893. Serial No. 472,605. (No model.)

Be it known that I, ARTHUR F. PURDY, a citizen of the United States, residing at Lawrence, in the county of Santa Clara, State of California, have invented a new and useful Book for Stamps, of which the followingis a full, clear, and exact description.

This invention relates to an improved form of book for the preservation of postage stamps, and` it hasfor its object to provide a device ofthis class which shall possess superior advantages in point of simplicity of construction, as well as inexpensiveness and general eiciency.

Heretofore no successful simple means have been invented for the proper preservation of postage stamps in the sheet form, therefore, to enable postmasters and others to keep such stamps dry, and to prevent them from curling and adhering together, and at the same time to make it possible to refer readily to the stamps of the required denomination, is the prime object of my invention.

Further novelty resides in the peculiarities of construction and the combinations, arrangements and adaptation of parts, all as more fully hereinafter described, shown in the drawings and then particularly pointed out in the claims.

It will be seen from the accompanying drawings, and following description that the salesman can readily compute, by reference to the book, the number of stamps removed, and therefore the exact amount of sales.

In the accompanping drawings, in which similar letters of reference designate corresponding parts: Figure lis a perspective view of the book in a partly open position. Fig. 2 is a longitudinal section, and Fig. 3 is a plan view of the book with the cover removed.

Reference being had to the above figures, A A represent the cover of the book, which is made of card-board or other suitable light material. Situated between the faces A and A are the index sheets B B', made preferably of* card board, but of a thinner quality than that composing the cover, the number of sheets corresponding to the number of different denominations of stamps. Between the cover A and the rst index sheet B, are secured to the book by means of metal staples or other suitable means, a number of thin sheets C preferably of oiled paper or paper containing a small amount of oil, the blank marginsDof the stamp sheet E being fastened to the said sheets C. On the upper surface of each oiled sheet C, a sheet of stamps is secured, as above therefore each of the latter sheets is separated from, and prevented from adhering to, the adjacent one by means of the oiled sheet, the oil in the latter prevent` ing the stamps from adhering to it. The object of the indexed sheets B B is to separate the stamps of dilerent denominations and to enable the postmaster to refer readily to the particular stamps which he desires to remove.

It is my intention to manufacture the book of a size sufficiently large to accommodate sheets of one hundred ordinary one or twocent stamps, or fifty of the Columbian issue. For the principal postoftlces, books of a larger size may be deemed necessary. In order to enable the salesman to compute readily the amount of sales, I have the series of numerals F, F and F placed on the margins of the index sheet B, F-F being an increasing arithmetical series, the common difference of` which is the denomination of the stamp, and the series F having a vcommon difference equal to the denomination of stamp multiplied by the number of stamps in a horizontal row; therefore, it will be readily seen that if the number of stamps sold be less than one horizontal row, the amount of sales is ascertained by reference to the series of numerals F or F while if one or more horizontal rows be removed, the salesman refers to the vertical series of numerals F.

I do not desire to confine my invention to any particular number of oiled or index sheets composing the book, as the number of the former is regulated by the number of stamps of each denomination required, while the latter is regulated by the number of denominations of stamps. For the sake of simplicity, I have represented in the drawings a book capable of holding merely one and two-cent stamps.

By reference to Fig. 3, it will be seen that I have constructed the oiled sheets C smaller than the index sheet B, in order' that the series of numerals F, F and F may be visible at the margin of the sheet C.

I am aware that changes in the size, loca- IOO 4tion and proportion of the parts of the invention herein shown and described can be made Without departing from the spirit, or sacrificing the advantages thereof, and I therefore reserve the right to make such changes and alterations as fairly fall Within the scope of my invention.

It will be readily seen from the foregoing description, that I have provided a very simple, effective, and inexpensive device, by the use of which postage stamps, in the sheet form, may be prevented from curling and adhering together in Warm and moist Weather, and from being accidentally detached from the sheet, the invention further affording a simple means for preserving an exact record of the number of stamps removed and the stock on hand.

Having thus fully described my invention, What'I claim, and desire to secure by Letters Patent, is-

l. In a book for the preservation of postage stamps, the combination of the indexed sheets B B With the oiled sheets C, said indexed sheets being made of a material heavier than said oiled sheets, said oiled sheets being secured to said indexed sheets, substantially as and for the purpose described.

2. In a book for the preservation of postage stamps, the combination of the indexed sheets B B with the oiled sheets C, said .indexed sheets being made of a material heavier than said oiled sheets and having a margin extending beyond tWo or more edges of said oiled sheets, said margins being adapted to bear numerals or other characters substantially as and for the purpose set forth.

3. In a book for the preservation of postage stamps, the combination of the indexedsheets B B with the oiled-sheets C, said indexed sheets having a margin projecting beyond one or more edges of said oiled-sheets, said oiled-sheets being secured to said indexed-sheets, substantially as and for the purpose set forth.

4. In a book for the preservation of postage stamps, the combination of the indexed sheets B B with the oiled sheets C, said index sheets having the series of numerals F F F printed on their margins substantially as and for the purpose set forth. v

5. In a book for the preservation of postage stamps, the combination of the indexed sheets B B' with the oiled sheets C, said indexed sheets bearing the series of numerals F F and F", said oiled sheets being smaller than said indexed sheets, and secured to said indexed sheets substantially as and for the purpose set forth.
